The main installation is slightly different in 22.04LTS, insert the Ubuntu Server (LTS 22.04LTS Live) installation CD/USB/DVD and follow the onscreen instructions. If you don’t understand the questions asked by the installer put the keyboard down and switch everything thing off and go back to being a user. You will be asked to select.
Language Keyboard Type of Ubuntu Install - Choose "Install Ubuntu"
Use the cursor keys to configure the network interface with a static IP address. (set the IPv6 option to Do Not Use) Internet Proxy: Set to whatever you user (none if you don't user one) Make sure you select “Use Third Party Drivers” if you for example have an NVIDIA card. Select Install SSH server with relevant options (if you want to use certs etc)
When prompted choose
Use An Entire Disk
This will configure the system disk, with automatic boot / root / swap partitions. You can specify extra disks later and mount them if needed. You can also enter manual mode and select other disks and choose your mount points. You may want to set up LV volumes if you want to resize partitions later.
If you want to be safe, disconnect all disks apart from the one on which you want the do the install, (then add them later)
root@solaris:/home/sysadmin# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS sda 8:0 0 3.6T 0 disk /srv/media sdb 8:16 0 12.7T 0 disk ├─vg--backup-lv--cctv 252:0 0 1T 0 lvm /srv/cctv └─vg--backup-lv--backup 252:1 0 11.7T 0 lvm /srv/backup sdc 8:32 0 3.6T 0 disk └─vg--data-lv--data 252:2 0 3T 0 lvm /srv/data sr0 11:0 1 1024M 0 rom nvme0n1 259:0 0 465.8G 0 disk ├─nvme0n1p1 259:1 0 1G 0 part /boot/efi └─nvme0n1p2 259:2 0 464.7G 0 part /
You can edit the disk partitions before submitting to add further disks at specific mount points. Mount points used were.. (which in this case were manually configured as I did not want to lose existing data)
Prolong the life of SSDs with
nano /etc/sysctl.d/local.conf
And add this line
vm.swappiness=20
Make live with
systemctl restart procps.service
When prompted create the system login user / password The server will install the basics, set up your user / timezone etc. Eventually you will be prompted to Reboot.
Reboot Now
We need to add additional repositories so we can download all the nice pieces of software and grab all the security updates, we do this by editing the config file listing the repositories.
sudo nano /etc/apt/sources.list
Note: sudo elevates you to ROOT status, by typing sudo –s before you begin maintains your elevated status so you don’t have to keep typing sudo; nano is a simple text editor. Note that ‘#’ and ‘;’ indicates the line has been commented out.
Comment / Uncomment and repositories you wish to use.
Now we have to get Ubuntu to update its internal repository database
sudo apt update
Now we can do a full distribution upgrade which gets us all the latest patches and fixes.
sudo apt dist-upgrade
Say yes to accept the installation. The dist upgrade may take some time to install, You probably then want to update any of the minor packages.
sudo apt upgrade
Answer yes to any of the upgrade questions. After it is probably wise to reboot and make sure everything is still good. Especially as you have probably got your self an updated linux kernel.
sudo reboot
Check that SSH server is working, Run a PuTTY session to the server and check connectivity.
nano /etc/ssh/sshd_config
And change
# To disable tunneled clear text passwords, change to no here! PasswordAuthentication no #PermitEmptyPasswords no # Enable this is you only want to allow people to login using a PSK. ChallengeResponseAuthentication no
systemctl reload ssh
To reload ssh (after changing this file) - Do this securely via OpenVPN. Keep a session open while you test the new login.
NOTE: THIS IS NOW FIXED This step is not necessary if you select - use Third Party Drivers during the install.
nano /etc/default/grub
Update the relevant line … (this will force the console into VGA(ish) mode)
GRUB_CMDLINE_LINUX_DEFAULT="maybe-ubiquity vga=0x307"
Now update the grub loader
update-grub
nano /etc/sysctl.d/local.conf
Add the following line.
net.ipv4.ip_forward=1
Then to load this restart the procps service…
systemctl restart procps.service
Configure a network bridge to present a single interface to the world, this is handy for VMs / VPNs etc. as we only need to reference the bridge. (br0:) 24.04 uses netplan to configure its network configuration.
The following steps will set up a bridge with a static IP address.
Change to the netplan directory.
NOTE: You may need to set the DNS server to be the local router - until you have set up BIND, then you can go back and edit this again.
cd /etc/netplan nano 00-solaris.yaml (default netplan config)

Disable the cloud network configuration.
touch /etc/cloud/cloud-init.disabled
Update the permissions on the netplan config to remove the global r/w permissions
chomd 600 /etc/netplan/00-solaris.yaml
Apply the changes
netplan --debug apply
Reboot and check the network configuration with
ip addr
You should have an interface of br0: with the ip you specified.
root@solaris:/home/sysadmin# ip addr

Edit the file
nano /etc/hosts
Comment out the entry for 127.0.1.1 and replace it with a Global server value.
10.3.200.1 solaris.scottworld.net solaris
This allows autocomplete on shell command lines
nano /etc/bash/bash.bashrc
Uncomment the the section
# enable bash completion in interactive shells
if ! shopt -oq posix; then
if [ -f /usr/share/bash-completion/bash_completion ]; then
. /usr/share/bash-completion/bash_completion
elif [ -f /etc/bash_completion ]; then
. /etc/bash_completion
fi
fi
You need to log out and back in for this to activate
Install the smartmon package.
apt install smartmontools mailutils
List the disks with
lsblk
Edit the file
nano /etc/smartd.conf
Edit this and set up your monitoring You first must comment out the line that tries to check all drives, then add this below to check your individual disks.
# Local NVMe disks /dev/nvme0n1 -a -W 1,40,50 -m mark@scottworld.net -M diminishing -s (S/../../7/01) # Local SATA disks /dev/sda -a -I 194 -W 1,40,50 -m mark@scottworld.net -M diminishing -s (S/../../7/02) /dev/sdb -a -I 194 -W 1,40,50 -m mark@scottworld.net -M diminishing -s (S/../../7/03) /dev/sdc -a -I 194 -W 1,40,50 -m mark@scottworld.net -M diminishing -s (S/../../7/04)
